Welcome to GTC Broadband


and Yes, it is true.  The telephone is not a required service to sign up for Internet.

Granby Telephone Company and GTC Broadband have been serving our community with the most advanced technology since 1904.  Internet was introduced in 1995 as dial-up Internet; you remember the ee-oo ee-oo ee-oo of the dial-up modems? Yet, today 100 Mbps is available in 70% of our service area.

Collectively, GTC and GTC Broadband have provided our friends and neighbors with over 110 years of experience and exceptional customer service.
